I Specification of Letters Patent. Application filed August 10,1905.- Serial No. 273,530.v

Patented June 25, 1907.

To a. whom it may concern:

Be it known that we, OTTO L. RAABE, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of N ewJersey, andGEoRGE F. READ, a citizen of the United States, and a resident of the city of. New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Delivery Mechanisms, fully described and represented in the following specification and the accompanying drawings, forming a part of the same- This invention relates to certain improvements in delivery mechanisms such as are used in connection with high speed printing machines for printing newspapers or similar publications.

In the production of newspapers, the unit employed is the single wide web which after being printed and. perfected is cut into sheets which carry two printed pages on one side and two printed pages on the other, these sheets being folded to produce a four page paper. Where a paper of more than four pages is desired, the number of webs is increased accordingly, it being usual to increase the width of the web, making it double, triple or quadruple, in order to make an eight, twelve, or a sixteen page paper, the web being slit and the separate webs produced by slltting being superposed and the product associated in a well-known manner.

The present development of the art'makes it easily possible to produce papers consisting of four, eight, twelve or sixteen, or even more pages, either, in the manner hereinbefore described, or by the collection of sheets during the deliveryiin a manner which is also well understood, the printing couples being provided with pairs of plates so imposed as to produce the four page sheets referred to, the web or webs running through said couples and to the superposing, associating and delivery mechanisms at the same speed.

The production ofpapers having a number of pages which is not an even multiple of four presents, however, more difiiculty, especially where it is desired to produce papers printed from couples carrying a single set of plates.

Six page papers are now roduced. by providing the couples with plates, the columns of the plates running around the cylinder, and these plates being uplicate sets of half width web. The half width web is associated with the single web and the two run together over a former. The folded product of this former is out between the ends of-successive pages, thus producing two six page papers for each revolution of the cylinders, the printing couples employed in this type of machine being usually rotary couples. If it were possible to make the cylinders small enough, a sixxpage paper might be produced in this manner from cylinders carrying only a single set of plates. The plates would, however, have to be substantially circular so as to occupy the full circumference of the cylinderan'd the machine would be of little use except for the particular product for which it was designed. These practical reasons, therefore, make it substantially impossible to produce a six page paper in this manner from a single set of plates. Ten page papers are produced in the same manner from duplicate sets of plates, printing on two single webs or a slit double wide web, and-aof plates and double the amount of stereotyping. Furthermore, when machines capacitated to produce ten page papers are considered, and this is the kind of paper which is more often used, a machine operating according to this mode becomes too GXPGDSIVG' to install in small oflices, for the reason that the cylinders have to be made lon enough to print two single webs and a hal width web,

or else two sets of cylinders, one printing a single web and the other a single web and a half width web, have to be used. Ordinarily,

therefore, where the problem of producing ten 1page papers is involved, quite a different met 0d of printing is resorted to. couples are employed, the cylinders of which carry a single set of plates with the columns running around the cylinders as before, these plates printing on a single wide web. A sec ond set of couples is employed in conjunction with this machine which prints on a half width web, this set of couples running at half the speed of the other cou lesand producing two single page sheets or each revolution of the cylinders. The sheets cut from Rotary the single wide web are collected in the usual manner and the single sheets from the half width half speed web are associated with them during collection. This method of producing ten page papers requires two sets of couples which must be arranged to run at different speeds and also makes a machine which is too large to be installed in small offices.

Generally speaking, the present invention has in view to produce a delivery mechanism for use in printing machines which shall be simple and economical to build, which will ena le products to be produced from a single sets of plates in which the sheets are not multiples of four, this being accomplished without the use of extra long cylinders and without the necessity of resorting to printing mechanisms which run at difierent speeds.

The invention further has in view the improvement of certain details of construction of delivery.

-With these and other objects not specifically referred to in view, the invention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed out.

Referring to the drawings-Figure 1 is a diagrammatic side elevation of a printing machine containing the improved delivery mechanism; Fig. 2 is a front elevation of the delivery mechanism illustrated in Fig. 1. Fig. 3 is a lan view of the construction illustrated in ig. 1. Fig. 4 is an enlarged detail view illustrating more particularly the construction of the cutting and folding mechanism employed, and also the specific means for delivering the sheets. Fig. 5 is a view similar to Fig. 4, illustrating a modified construction: ends of the cylinders illustrated in Fig. 5, and certain features of the operating mechanism therefor.

' 2 and 3 respectively are supplied with ink by the usual mechanisms indicated at, 5 and 6. The web indicated at W is supplied from a web roll mounted in any suitable manner- Each of the printing cylinders, as indicated in Fig. 3, carries a single set of plates the columns of which are arranged parallel to the axis of the cylinder. The specific construc- Fig. 6 is a detail view showing the- Fig. 7 is a view showing the 1 ends of the cylinders opposite those illus- 'ner.

tion illustrated is designed to produce either i As the machineis arranged'in the construction illustrated, it is designed to produce ten page papers. The cylinders therefore, carry at one end two pairs of plates and at the other end a single plate, the single plate occupying, of course, only one half the circumference of the cylinder. The machine is shown as printing on a web which is wide enough to be cut by suitable slitters, indicated at 7, intothree parts, these slitters 00- operating with the usual roll 8.

In the construction illustrated, the web is guided to the cylinders by means of a guide roll 9 and tapes 10, this construction being the usual one. After leaving the slitters, the three webs, which are marked W, W W pass onward,'their movement and direction being controlled by such devices as'are commonly employed for guiding and controlling webs. In the particular construction illustrated, the webs W, 'W pass under a guide roll indicated at 11, and the web passes under a guide roll indicated at 12, this roll being lower than the guide roll 11. The web WV passes around a turner bar, indi cated at 13 and over a guide roll 14. The web W passes over a turner bar 15 and around a guide roll 16, these webs, by the action of these bars and rolls, are so led as to be superposed and are associated as they pass between a pair of nipping rolls illustrated at 17. After these webs W are associated, either by the devices hereinbe- 22. The shaft 22 is provided with a driving gear 23 (see Fig. 7) and this gear is in mesh with one of the gears of a train,'the lower one of which is marked 24. This gear is mounted on a shaft 25 indicated in dotted lines in Fig. 1, which derives its power from the couple driving mechanism. The shafts 21 and '22 are intergeared in the usual man- In the particular construction shown,

IIO

.(IQTS 19, 20, the cylinder 19 being mounted on-a shaft 21 and the cylinder 20 ona shaft the cylinder 19 is provided with a cutting blade 26 which cooperates with a cutting wood 27 mounted on the cylinder 20.

The cylinder 20 is provided with sheet or web taking devices which may be of any suitable description. In the construction shown, these sheet taking devices consist of pins 28,

these pins being operated from a' rock lever 29 which runs at proper times on a suitable cam (not shown), andby aspring rod construction 31 also ofjusual form. The "cylinder 20 is or may be providedwith folding dcvices of any suitable description. In the particular construction shown, these folding devices consist of a double blade 32 mounted on a shaft 33 suitably journaled in the cylinder, this shaft being operated by a two-armed rocker 34, the bowls of which cooperate at suitable times with a cam, not shown. This double folding blade 32 tucks the sheets between a pair of rolls 35. In the particular construction shown, carrying tapes 36 are supported in part by thesero ls, these carrying tapes carrying the folded sheets into positionwhere they receive another foldby a folding .blade, not shown. This blade cooperates with rolls 37 which deliver the sheets to an S-fly 38. This construction is of usual form and any other suitable construction may be substituted for it.

It will be understood that the webs W, W and W are, since they are printed by the same couples, running at the same s eed. The present invention contemplates, ow ever,cutting from one of thewebs, in this instance, the web W3, sheets which are less in size than the sheets cut from the other web or webs. In the particular construction shown, the web W is shown as receiving 1mpressions from a single page plate, while the other webs are shown as receiving impressions from a painof page plates. It follows, therefore," that the web W will, in the construction shown, as it passes to the web forwardin devices, bear single page impressionswliich are halfthe size of the two pa e impressions on the other webs, these smg e pageg impressions alternating With blank s aces-j on the web .of thesame size, these b an'k spaces appearin clearly in Fig. 3 and being marked 39. When, therefore, mechanism of the specific character illus rated is employed in carrying out the inve 'tion," it wil bc'desirable that the apparatus for cutting the web W into sheets be such as to cut and transfer the printed sheets from the web be associated with- W, so that they ma sheets cut fromthe 0t er web or webs. the s ecific construction shown, after the web V8 leaves the roll' 1 1 before referred to it passes around a turner bar 40 and a ide roll 41. From this guide roll 41, the we W asses between a air of drawing rolls 42, and 10m these rolls etween a pairof cylinders 43, 44. The cylinder 43 is mounted on a shaft 45 suitably journaled in the frame and the cylinder 44 1s mounted on a similarshaft 46. These cylinders43, 44 are of the same size as the cylinders 19, 20 before referred to and aredriven therefrom, the shaft 22 of the 20 being provided with a gear'47 which'nie'shes'witha gear48 on the shaft 45 i cut ting woods 50 on the cylinder 44. As has been indicated, in the specific construction illustrated, these cylinders 43, 44'not only out half size sheets from the web W but they transfer the printed sheets to be associated with the sheets out from the webs W, W and vthey also take care of the un rinted sheets.

In order to accom lish this, 1n the particular construction s own, each of thecylinders 43, 44 is provided with sheettaking devices. While these sheet takin devices may be varied in construction, as shown the cylinder 43 is provided with a set of sheet taking pins 51, these pins being operated from a rock lever 52 and a spring rod 53 as is usual.

The cam for operatin the rock lever 52v is indicated at 54 (see Fig. 4.) The sheet taking devices on the cylinder 44 as shown consists of a set of stationary pins 55. It has been stated that the printed sheets cut from the web W are half the size of the sheets cut from the webs W, W. As a matter of fact, however, they are little more than I half the size, thus allowing for a slight lap for pasting. The sheets cut from the web W may be associated with the sheets cut from the webs W, W either by laying their lead- "ing edges on about the fold line of the sheets from "W, W the leading-edges, however, projectingsufficiently over the fold-line to make a pasting lap, or they may be associated by-bringing their leading edges into register with the leadingedges of the sheets cut from the sheets of webs W W in which cases, the rear edges of the sheets from the web W will slightly overlap the fold line of the sheets cut from the webs V, W. Constructions by which both these methods of associations may be carried out are illusthe sheets being thus-transferred from the cylinder 43 to the cylinder 20. In the rotation of trated. In the construction shown in Fig. 4, pins 28 take the sheets which have been om the web W from the pins 51-, the I the cylinder 20, the pins 28 lay the leading edges of the sheets cut from the web W against the leading edges of the webs W, W

as these webs are entering the nip of the cyl inders 19, 20. As the cylinders '19, 20 ro-' tate, these sheets and the webs W, W are carried around until the tail of the sheet cut from the web W and the middle portion of the sheets to be cut from the webs W, 'W

arrive opposite the rolls 35. At' this time, I

the tucking blade operates and thereafterthe' blade 26 severs the sheets from the webs W, W This operation produces, in the particular construction shown, a ten page paper with a single page sheet inset into the inner one of a pair of double sheets cut from the webs W, W this product being shown between the tapes 36 in Fig. 4. In the construction shown in Fig. 5, the cylinder is provided with the pins28 before described, and with an extra set of-pin's 57, thesepins being mounted on arms 58 carried on a shaft 59. This shaft is operated from a rock arm 60 carrying a bowl. which works on'an interior cam formed on a ring-61 (see Fig. 6) secured to the main frame by brackets 62, and by a spring rod construction of the usual type, indicated at 63. In the 0 eration of this form of the construction, tie leading edges of the webs W, W are taken by the pins 28 and the leadingedge of the sheet cut from the web W is taken from the pins 51, by the pins 57, the rotation of the cylinders being so timedthat the leading edge of the sheet cut from the web W is laid against the webs W, W at about the center of the sheets.

to be cut from the webs W, W In other respects the operation of the construction shown in Fig. 5 is the same as that illustrated in Fig-'4, w

The unprinted sheets cut from the web W may be led out of the machine in any suitable manner. shown, they are taken from the cylinder 44 by a stripper 64, this stripper being mounted on a shaft 64 which is operated by means of an arm 65, this arm being connected to a cam rod 66, the lower end of which is forked and straddles a shaft 67, this shaft carrying a cam 68 which operates the rod. This shaft 67 is driven by a-large gear 69 which is in of the usual type.

mesh with a gear 69 mounted on the shaft 22 before. referred to. The stripper directs the sheets in an unfoldedcondition between a pair of rolls 70 which in turn delivers them to a. fiy 71. This fly is mounted on a rock shaft 72 which is operated through a cam rod 73 from a cam 74 on the shaft 67 before re-, ferred to, and by a spring rod construction 75 The fly (lelivery'is a desirable one for the reason that'it delivers the un rinted sheets flat so that they may be uti ized for .any suitable purposeafter they have issued from the machine. In order,

--however,to avoid frequent reciprocations of the fly, it is desirable that the cylinder 44 be run as a collecting cylinder and that the stripper be thrown in once in a predetermined number of revolutions of this cylinder.

For this reason, the shaft 67 is geared down,

r as shown. The stripper, therefore, remains out of operation during a number of revolutions of the cylinder 44,, allowing the unprinted sheets to be collected thereon. If desired ,tapes 76 or other similar devices ma be employed to assistin retaining the co lected sheets on the cylinder 44-. i v

Curved sheet guiding brackets 77 of usual In the particular construction form may, if desired, be employed in connection with-the cylinder 20, and in the articular construction shown, a series of s eet guidingbrackets 78 are employed between the cylinders 43, 44, these brackets forming pathways for the sheets taken by these cylinders.

- In the particular construction shown, the web W has printed and unprinted spaces,

the unprinted spaces being cut up into sheets which, are-afterward piled by the fly 71 'on a table 79. If desired, however, the cylinders 2, 3 which carry the plates for the ten page paper, may be-provided with other plates which will print hand bills,'posters, or' other commercial printin While the mechanism i lustrated has been described particularly in connection with the production of a ten page paper, it is obvious that it can be used by making the web narrower, so as to omit the web IN, to print papers of six pages. It is also apparent that by providing the cylinders with a full complement of plates, a twelve page paper can be produced. In this case, however, the web N would be a full printed web and instead of being led through the rolls 42, would be led over a guide 80 indicated in Fig. 2, from which guide it will be led directly between the rolls 17 and there associated with the webs W, W When the machine is used in this manner, the rolls 43, 44 might either be thrown out or allowed to run idly, as desired. While, furthermore, delivery mechanisms embodying the invention are particularly adapted for use with rotary printing couples, 1 they may be used with couples having other than rotary members. Changes and variations may be made in the constructions by which the invention is carried 'into effect. The invention is not, therefore, to be limited to the particular constructions hereinshown and described.
